Effect of quercetin against lindane induced alterations in the serum and hepatic tissue lipids in wistar rats

Objective:To assess the effect of quercetin(flavonoid) against lindane induced alterations in lipid profile of wistar rats.Methods:Rats were administered orally with lindane(100 mg/kg body weight) and quercetin(10 mg/kg body weight) for 30 days.After the end of treatment period lipid profile was estimated in serum and tissue.Results:Elevated levels of serum cholesterol, triglycerides,low density lipoprotein(LDL),very Low Density Lipoprotein(VLDL) and tissue triglycerides,cholesterol with concomitant decrease in serum HDL and tissue phospholipids were decreased in lindane treated rats were found to be significantly decreased in the quercetin and lindane co-treated rats.Conclusions:Our study suggests that quercetin has hypolipidemic effect and offers protection against lindane induced toxicity in liver by restoring the altered levels of lipids.The quercetin cotreatment along with lindane for 30 days reversed these biochemical alterations in lipids induced by lindane.

Therapeutic Potential of the Medicinal Plant Tinospora cordifolia–Minireview

For thousands of years,plant based herbal medicines have been utilized by millions of people all over the world.Plant materials or products are used in different folk/traditional medical systems,such as the Chinese,African and Indian medical systems,like Siddha,Ayurveda,Unani,and Homeopathy.Tinospora cordifolia(TC)is a medicinal plant belonging to the family Menispermaceae.It is a big deciduous,climbing shrub growing prevalently in the tropical part of Indian subcontinent regions such as India,Pakistan,Nepal,Bhutan,Bangladesh and Srilanka,and in Myanmar,and China.Guduchi,Giloy,Shindilkodi,and Amritha are all the common names for this plant.Extracts from different parts of this herbal plant have been used to treat many diseases.In Ayurvedic medicine,extract from this plant is used for preparing“rasayanas”,which is known to cure diabetes,skin diseases,allergic conditions,jaundice,cardiovascular diseases,rheumatoid arthritis,poisoning,and microbial infections.T.cordifolia has a many bioactive phytochemicals that have been isolated from its aerial parts and roots.Many bioactive principles have been reported from this plant which belong to various classes like alkaloids,aliphatic compounds,diterpenoid lactones,phenolics,flavonoids,glycosides,sesquiterpenoids,lignans,steroids and polysaccharides.T.cordifolia possesses medicinal properties such as antioxidant,antiallergic,antiinflammatory,antimicrobial,antiviral,antidote,antitumor,antileprotic,antispasmodic,and antidiabetic properties.The present review will provide a comprehensive therapeutic potential of T.cordifolia.

Reversal of doxorubicin resistance in lung cancer cells by neferine is explained by nuclear factor erythroid-derived 2-like 2 mediated lung resistance protein down regulation

Aim:Development of multi drug resistance and dose limiting cardiotoxicity are hindering the use of Doxorubicin(Dox)in clinical settings.Augmented dox efflux induced by lung resistance protein(LRP)over expression has been related to multi drug resistance phenotype in various cancers.An alkaloid from lotus,Neferine(Nef)shows both anticancer and cardioprotective effects.Here,we have investigated the interconnection between nuclear factor erythroid-derived 2-like 2(NRF2)and LRP in Dox resistance and how Nef can overcome Dox resistance in lung cancer cells by altering this signaling.Methods:Anti-proliferative and apoptotic-inducing effects of Nef and Dox combination in Parental and Dox resistant lung cancer cells were determined in monolayers and 3D spheroids.Intracellular Dox was analyzed using flow cytometry,siRNA knockdown and western blot analysis were used to elucidate NRF2-LRP crosstalk mechanism.
